Red Team Assessments That Reveal How You'd Actually Be Breached

Penteros simulates realistic attacker behavior to uncover how your systems can actually be breached — and what to fix first.

We show how an attacker gets from entry to sensitive data — step by step.

Led by a practitioner with 30+ years in systems, infrastructure, and security — with AI-assisted execution for deeper coverage in the same engagement.

The Problem

Most Security Testing Misses What Actually Matters

Point-in-Time Testing

Traditional pentests capture a single snapshot, missing how your environment actually evolves between assessments.

Noise Without Context

Vulnerability scanners produce long lists of findings without showing which ones actually create risk in your specific environment.

No Attack Path Visibility

Most findings do not show how an attacker actually moves through your systems from initial access to impact.

Actionability Gap

Security teams need real attack path visibility and prioritized fixes, not just issue lists without business context.

What We Do

AI-Assisted Offensive Security Assessments

We identify how weaknesses can be combined into real-world breach scenarios — not just individual vulnerabilities.

Test Like a Real Attacker

We simulate realistic adversarial behavior against your environment, not just checkbox scanning.

Chain Vulnerabilities into Attack Paths

We connect individual weaknesses into multi-step compromise scenarios that reflect how breaches actually happen.

Prioritize What Actually Matters

We rank risks by real exploitability and business impact, so your team fixes the right things first.

Process

How It Works

Step 01

Scope the Environment

We define target systems, rules of engagement, and assessment boundaries.

Step 02

Execute AI-Assisted Attacks

We simulate realistic attacker behavior using AI-guided offensive operations.

Step 03

Identify Real Attack Paths

We connect weaknesses into multi-step compromise scenarios.

Step 04

Deliver Findings & Walkthrough

We provide a prioritized report and review the results with your team.

Example

Example Attack Path

An attacker gains access through exposed credentials, pivots to internal services, escalates privileges, and reaches sensitive data. Penteros maps this path so your team can shut it down quickly.

Comparison

Beyond Scanners. Beyond Traditional Pentesting.

Scanners

  • Static checks
  • Isolated findings
  • Noisy output
  • No attacker logic

Traditional Pentesting

  • Limited time window
  • Human-only coverage
  • Partial attack path visibility

Penteros

  • Senior practitioner, 30+ years
  • Attack path discovery
  • Prioritized, exploitability-based findings
  • AI-assisted for deeper coverage

Deliverables

What You'll Receive

Each assessment shows how a real attacker could move through your environment and what to fix first.

Attack Path Analysis

Step-by-step breakdown of how vulnerabilities are chained into a real breach scenario.

Prioritized Findings

A focused list of risks based on real exploitability, not generic scanner output.

Remediation Guidance

Clear, actionable fixes ranked by impact so your team knows what to address first.

Delivered as a structured report and walkthrough focused on real, exploitable risk.

Example Findings

Assessment Findings PENTEROS-2026-001
Critical
Credential Reuse to Admin Panel
Exposed service account credentials grant admin-level access to internal management interface. Rotate credentials and enforce MFA.
High
Lateral Movement via Misconfigured IAM
Overly permissive IAM role allows pivot from staging to production. Scope role to minimum required permissions.
Medium
Unpatched Dependency in API Gateway
Known CVE in API gateway dependency enables request smuggling. Update to latest patched version.

Engagement & Investment

Scoped, Fixed-Price Engagements

Every engagement is fixed-price after a scoping call, with a signed NDA and written authorization before any testing begins.

Focused Assessment

From $10,000

A single application, API, or defined scope. Typically 1–2 weeks. Attack-path report, prioritized findings, and a review call.

Attack-Path / Red Team

Up to $20,000

A broader environment across web, cloud, APIs, and internal services. Typically 2–3 weeks. Full attack-path analysis from entry to sensitive data.

How Pricing Works

We scope on a short call, then quote a fixed price within this range based on environment size and objectives — no hourly surprises.
